Web API Developer

Greymass is looking for a developer with strong backend development skills and data modeling experience to help bring both Robo and Fuel to the next level. Fuel is a product that Greymass developed to be a turn-key solution for resource billing on Antelope chains, written in Node.js + MongoDB, while Robo is a scalable blockchain history provider written in Golang + BadgerDB. These projects are intended to provide value to users and developers on Antelope-based chains.

About the role:

• For Robo, you will be responsible for abstracting the indexing processes to allow for flexible custom API endpoints, and the creation of custom indices for Greymass purposes (e.g. balance APIs)
• For Fuel, you will be responsible for standardizing the API endpoints and defining standards, improving estimation and billing costs, and adding new features such as pay-as-you go billing via fiat subscriptions or prepayments
• For open-source projects, you will prepare and package the codebase for public release, including documentation and automation for deployment
• In the future, you will build or modify API plugins within nodeos to extend functionality

What we’re looking for:

• Experience with Golang and/or Node.js
• Familiarity with REST and WebSocket API architectures
• Comfortable working in an independent and self-directed manner
• C++ experience is a plus for working within nodeos
• Experience working within the blockchain community or on open-source projects is a plus
